[0033] In the specific embodiment of the utility model, the support 1 is the main structure of the whole unmanned aerial vehicle, providing the function of supporting and connecting other components. The motor 2 provides power for the unmanned aerial vehicle, driving the blade to rotate, so that the unmanned aerial vehicle can fly. The blade 3 is driven to rotate by the motor, generating lift to lift the unmanned aerial vehicle, and controlling the attitude and movement direction of the unmanned aerial vehicle by changing the rotation speed or angle. The bottom plate 5 is located below the support, mainly used for supporting and protecting the internal device, and also serving as the mounting platform of the box 6 and other lower components. The box 6 is used as a container for loading fire extinguishing bombs, and is also part of the release mechanism. It is fixed to the bottom plate by bolts, ensuring safety and stability during air transportation. The four sleeves 13 are used to contain and position the fire extinguishing bombs 15. They ensure that the fire extinguishing bombs do not move randomly during transportation, thereby ensuring safety. The two cross plates 14 are connected between the sleeves and the box, playing a role in strengthening the structural strength, and may also participate in limiting the position of the fire extinguishing bombs. The fire extinguishing bomb 15 is the key load of the unmanned aerial vehicle for executing tasks, used for extinguishing fires. The release component is arranged at the lower end of the box, responsible for opening the closure plate according to the preset conditions or remote instructions, so that the fire extinguishing bomb can be smoothly thrown out of the unmanned aerial vehicle.

[0034] For details, please refer to Figures 1-4 The release component includes a mounting seat 8, a closure plate 9 and a connecting assembly. The mounting seat 8 is fixedly connected to the lower end of the box 6, the closure plate 9 is connected to the lower end of the box 6, the mounting seat 8 and the closure plate 9 are rotationally connected through a rotating shaft, a protective pad 10 is fixedly connected to the upper end of the closure plate 9, and the connecting assembly is arranged at the side end of the box 6 to realize the opening of the closure plate 9.

[0035] In this embodiment: the mounting seat 8 serves as the fulcrum of the rotation of the closure plate 9. It provides stable connection between the closure plate and the box, and ensures that the closure plate can rotate smoothly around the rotating shaft to realize the opening and closing actions. The closure plate 9 functions to seal the box when the unmanned aerial vehicle carries the fire extinguishing bomb to fly, preventing the external environment from affecting the internal fire extinguishing bomb. When it is necessary to release the fire extinguishing bomb, the closure plate rotates around the rotating shaft to open, allowing the fire extinguishing bomb to fall smoothly from the box. The protective pad 10 directly contacts the fire extinguishing bomb. The main function of the protective pad is to protect the fire extinguishing bomb from damage, especially to provide a cushioning effect when the unmanned aerial vehicle takes off or encounters bumps; at the same time, it can also reduce the friction or collision between the closure plate and the fire extinguishing bomb, ensuring the safety of the fire extinguishing bomb. The connecting assembly is used to control the opening action of the closure plate 9.

[0036] For details, please refer to Figures 1-4 The connecting assembly includes a gas cylinder 7, a connecting seat 11 and a spring 12. The gas cylinder 7 is fixedly connected to the side end of the box 6, the connecting seat 11 is fixedly connected to the side end of the closure plate 9, the output end of the gas cylinder 7 is connected to the connecting seat 11, and the spring 12 is connected between the connecting seat 11 and the gas cylinder 7.

[0037] In this embodiment: the cylinder 7 is the main power source of the connecting assembly. It generates linear motion through internal pressure changes, usually gas or hydraulic, to drive the opening action of the closure plate 9. The output end of the cylinder is connected to the connecting seat 11, when the cylinder extends or retracts, it will drive the closure plate to rotate around the rotating shaft, so as to realize the opening or closing of the closure plate. The connecting seat 11 serves as a connecting bridge between the cylinder 7 and the closure plate. It transmits the force from the cylinder to the closure plate, so that the closure plate can move in the expected way. In addition, the connecting seat also provides a fixed mounting point for the spring 12, so that the spring can maintain appropriate tension when the cylinder retracts, and assist the closure plate to reset when needed. The spring 12 plays a role in buffering and assisting reset. When the cylinder pushes the closure plate to open, the spring will be stretched; in the case of cylinder retraction or loss of pressure, the spring can help the closure plate quickly return to the closed position.

[0038] For details, please refer to Figures 1-4 The upper end of the closure plate 9 is fixedly connected with a protective pad 10, which is matched with the fire extinguishing bomb 15.

[0039] In this embodiment: the main function of the protective pad 10 is to provide cushioning between the fire extinguishing bomb and the closure plate, preventing damage to the fire extinguishing bomb caused by vibration or impact during the take-off and landing of the unmanned aerial vehicle or during flight. Especially when the unmanned aerial vehicle encounters air turbulence or lands, the protective pad can effectively absorb the impact force and ensure the integrity of the fire extinguishing bomb.

[0040] For details, please refer to Figures 1-4 The outer diameter of the protective pad 10 is equal to the inner diameter of the sleeve 13.

[0041] In this embodiment: since the outer diameter of the protective pad 10 is completely matched with the inner diameter of the sleeve 13, this design can ensure the positioning of the fire extinguishing bomb inside the sleeve 13. This can prevent unnecessary movement or rotation of the fire extinguishing bomb during transportation, maintain its stable position, and thus ensure the accuracy and consistency of the release. The equal outer diameter and inner diameter size means that there is almost no gap between the protective pad 10 and the sleeve 13, which helps to form a relatively closed space. If the unmanned aerial vehicle encounters changes in air flow or air pressure during flight, the close fit can help reduce the influence of the external environment on the fire extinguishing bomb, such as dust, moisture or other contaminants entering the inside of the sleeve.

[0042] For details, please refer to Figures 1-4 The upper end of the bracket 1 is fixedly connected with a connecting frame 4, and the upper end of the connecting frame 4 is provided with a battery 16.

[0043] In this embodiment: the bracket 1 is the basic structure of the entire unmanned aerial vehicle, which provides stable support for all components mounted thereon. By fixing the connecting frame 4 to the upper end of the bracket, the stability of the connecting frame and the battery 16 above it is ensured, even when encountering bumps or airflow changes during flight, wherein the battery 16 is the power source of the unmanned aerial vehicle, located at the upper end of the connecting frame 4, which can provide a centralized power supply point for the unmanned aerial vehicle.

[0044] The working principle and use process of the utility model: first, the operator issues a take-off instruction when in use, the unmanned aerial vehicle ascends according to the predetermined route, and the unmanned aerial vehicle automatically navigates to the specified target area according to the GPS and other navigation equipment, maintains stable flight in the process, avoids unnecessary bumps affecting internal equipment, when the unmanned aerial vehicle reaches the predetermined drop point, the system will automatically activate the release assembly according to the preset conditions such as geographical coordinates, time or other trigger factors, the cylinder 7 receives the instruction and starts to act, pushes the connecting seat 11, makes the closing plate 9 rotate around the rotating shaft and opens, the spring 12 assists this process, ensures that the closing plate can be opened smoothly and quickly, with the opening of the closing plate, the fire extinguishing bomb 15 slides out of the sleeve 13 and is thrown to the ground target, after all the predetermined fire extinguishing bombs are dropped, the unmanned aerial vehicle will return to the base according to the return route.

[0045] Finally, it should be noted that: the above only for the preferred embodiments of the utility model, and not for limiting the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can modify the technical scheme recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features.
